Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge construction anti-falling device. Background Art

[0002] After long-term use, the surface of the bridge will be damaged, so the damaged position needs to be repaired and maintained. When repairing the bridge surface, the original road surface needs to be broken and removed, and then the road surface is re-cast. When the bridge deck is broken, it is easy to produce debris and gravel. At the same time, the debris and gravel are easy to splash under the bridge and cause harm to pedestrians under the bridge. Therefore, during the construction process, anti-fall devices need to be installed on both sides of the bridge to form a shield;

[0003] Most of the existing anti-fall devices are protective nets, which are installed on the side walls of the bridge on both sides of the construction site to form a shielding protection. However, in actual use, the size of the protective net is fixed and not adjustable, so it cannot adapt to construction areas of different sizes for protection. At the same time, when changing the construction position, the protective net needs to be disassembled and transferred, which is troublesome and affects efficiency. Therefore, we propose a bridge construction anti-fall device. Utility Model Content

[0004] The utility model aims to provide a bridge construction anti-falling device, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge construction anti-fall equipment, including an adjustment plate, limited position frames are fixed on both sides of the bottom of the adjustment plate, movable plates are connected to both sides of the top of the adjustment plate, a storage shell is fixed on the top of the movable plate, a reel is rotatably installed in the inner cavity of the storage shell, a protective net is arranged between the two storage shells, and both ends of the protective net are respectively movable through the storage shells on both sides and are sleeved on the corresponding outer walls of the reel.

[0006] By adopting the above technical solution, the limit frame is put on the side wall of the bridge construction position, and then the adjustment plate is used to drive the movable plates on both sides to adjust the position, so that the distance between the storage shells on both sides can be adjusted, and the length of the release protection net can be adjusted to adapt to the length of the construction position, thereby forming a comprehensive and effective protection to prevent gravel from splashing under the bridge and causing harm to pedestrians.

[0007] As a preferred embodiment of the utility model, a second roller is fixed to the top of the inner cavity of the limit frame, a carrier plate is provided on both sides of the inner cavity of the limit frame, a first roller is fixedly connected to one side wall of the carrier plate, a screw rod is threaded through the side wall of the limit frame, and the inner end of the screw rod is rotatably connected to the other side wall of the carrier plate.

[0008] By adopting the above technical solution, when the limit frame is put on the side wall of the bridge, the rotating screw can drive the carrier plate to move and adjust the position, so that the first rollers on both sides are clamped tightly on both sides of the side wall of the bridge, so that the device can be installed firmly. When it is necessary to move, the screw is slightly loosened, and then the device is pushed so that the first roller and the second roller can roll along the side wall of the bridge, thereby realizing rapid position change and improving operating efficiency.

[0009] As a preferred embodiment of the present invention, a limiting rod is fixed to one side of the outer wall of the carrier plate, and the limiting rod movably passes through the limiting frame.

[0010] By adopting the above technical solution and setting the limit rod, the movement stability is high when the rotating screw drives the carrier plate to move.

[0011] As a preferred embodiment of the utility model, a limiting slide groove is provided on the top of the adjustment plate, and matching limiting slide blocks are inserted on both sides of the inner cavity of the limiting slide groove. The side wall of the limiting slide block is fixedly connected with an electric push rod, the outer end of the electric push rod is fixedly connected to the inner wall of the limiting slide groove, and the top of the limiting slide block is fixedly connected to the corresponding movable plate.

[0012] By adopting the above technical solution, the electric push rod can drive the limit slider to slide in the limit slide groove, thereby driving the movable plates on both sides to adjust the position, thereby adjusting the length of the released protective net.

[0013] As a preferred embodiment of the utility model, torsion springs are fixedly mounted on the outer walls at both ends of the reel.

[0014] By adopting the above technical solution and setting the torsion spring, the reel has a certain torque, so that the protective net can be tightened to improve the protective effect.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The bridge construction anti-fall device of the technical solution of the present application drives the limit slider to move through the electric push rod, thereby driving the movable plates on both sides to adjust the position, so that the position of the storage shells on both sides can be adjusted, and then the length of the released protection net can be adjusted, so that it can adapt to construction areas of different lengths for protection, thereby improving the protection effect of the device;

[0017] By putting the limit frame on the side wall of the bridge and then rotating the screw rod, the first rollers on both sides can be clamped on both sides of the side wall of the bridge, so that the device is stable. At the same time, when the position needs to be changed, the screw rod is loosened, and the first roller and the second roller are used to move the device along the side wall of the bridge, so that the position change operation is convenient and fast, and the operation efficiency is improved.

[0029] Furthermore, the outer walls of both ends of the reel 22 are fixedly sleeved with torsion springs 23. The setting of the torsion springs 23 enables the reel 22 to have a certain torque, so that the protection net 21 can be tightened to improve the protection effect;

[0031] like Figure 1 and 2 As shown; a second roller 33 is fixed to the top of the inner cavity of the limit frame 3, and a carrier plate 31 is provided on both sides of the inner cavity of the limit frame 3.
